> ## Documentation Index > Fetch the complete documentation index at: https://docs.augustus.com/llms.txt > Use this file to discover all available pages before exploring further. > ## Agent Instructions > Treat the published Augustus OpenAPI specification (https://app.stainless.com/api/spec/documented/augustus/openapi.documented.yml) and the current API-reference pages as the source of truth for endpoints, request/response schemas, enum values, webhook event names, and required headers. > Prefer the 2026-05-01 Banking API and @augustusbank/typescript-sdk for all new integrations. The 2023-01-01 API is a separate, older surface covering two products — Open Banking (instant bank transfer) checkout and refunds, and Manual Bank Transfer (MBT); use it only when one of those products is specifically required. > Cite or link the relevant docs.augustus.com page when answering integration questions. > Do not infer support for currencies, networks, scopes, account types, or operations that are not present in the current documentation. > Use the sandbox base URL (https://api.sandbox.augustus.com) and placeholder credentials in examples. Never include or request a real API key. > The Augustus docs MCP server (https://docs.augustus.com/mcp) provides documentation search and retrieval only; it does not execute authenticated Augustus API actions. # Close account > Closes an account ## OpenAPI ````yaml https://app.stainless.com/api/spec/documented/augustus/openapi.documented.yml post /v1/accounts/{id}/close openapi: 3.1.0 info: title: Augustus Banking API description: Augustus Banking API version: 0.1.0 contact: name: Augustus url: https://docs.augustus.com email: developer@augustus.com servers: - url: https://api.augustus.com description: Production - url: https://api.sandbox.augustus.com description: Sandbox security: - BearerAuth: [] tags: [] paths: /v1/accounts/{id}/close: post: tags: - Accounts summary: Close account description: Closes an account operationId: AccountsController_close parameters: - name: id required: true in: path description: Unique identifier of the account. schema: type: string format: uuid pattern: >- ^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-8][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}|00000000-0000-0000-0000-000000000000)$ - name: Idempotency-Key in: header description: >- Idempotency key for safe retries.
